WETNESSES HORNE (TNTT STT FFTQ WINDOW'.

To all whom it may concern:

Be it known that I, GUSTAV HOEHNE, a citizen of Germany, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Windows, of which the following is a specification.

My invention relates to window construction. Its object is to provide a window in which the upper and lower sashes are adapted to stand in the same plane when the window is closed and to be locked against movement; in which the sashes may be readily moved up or down to allow for ventilation either at the top or bottom, or both; which sashes may be counter balanced and at the sime time permit the independent movement of either sash; and in which window either sash may be readily turned on a pivot into the room to enable the window to be cleaned without the operator having to hang outside the window; and which window construction shall be simple, cheap and practical.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is an elevation, showing my window construction. Fig. 2 is a section taken on line XX of Fig. 1, showing the lower sash in dotted position when latch is released. Fig. 3 is a similar view showing the lower sash in an extended position. Fig. 4 is a section on line 1 3 of Fig. 1.

A represents a window casing which is of suitable size shape and material; 2 and 3 are respectively the upper and lower sashes which are adapted normally to stand in the same plane and to be locked by suitable means, as a spring latch or catch 4.

When the window is closed the upper sash 2 is supported between the wedge shaped parting strips 5 and the outside ledge 6 of the window casing. The lower sash is designed to spring outward at the top and beneath the lower rail of the upper sash when the latch 4 is released, so that the lower sash may be raised past the upper sash and to slide between the parting strips 5 and the inside ledges 7. These inside ledges 7 however, extend only approximately the length of the upper sash when the latter is closed; these ledges 7, however, are continued downward by hinged rails 8,

which are wider at the bottom than at the top, to form a contracted or tapered runway for the lower sash. That is to say, when the hinged rails 8 are turned into operative closed position the space back of these rails 8 and between them and the rear or outer ledge 6, will correspond approximately to the thickness of a sash rail; this widened end of the hinged rails 8 forming this contracted runway will operate to lead the lower end of the lower sash into the plane of the upper sash so that when the top of the lower sash is pushed outward underneath the lower rail of the upper sash the two sashes will stand in the same plane, and the bottom of the lower sash will be prevented from rattling.

The hinged rails 8 are each preferably made right angular in cross sections with the front portion 9 of each rail adapted to rest fiat against the body of the window casing and forming a weather-proof joint.

The sashes are counter balanced so as to move easily, and so as to be moved either in unison or to be moved independently. As here shown, a window cord 10 is attached to each side rail of the top sash as at 11. These cords 10 are accommodated in suitable grooves in the side rails and run over pulleys 12 in the window frame, and each cord is looped to support a weight 13 hung over a pulley 14, which latter runs on the cord. The other end of the cord passes over another direction pulley 15 at the front of the parting strips 5; and down around a little direction pulley 16 adjacent to the lower edge of the top sash and in line with the parting strips, and connects with the lower sash as shown at 17. When the window is closed so that the two sashes stand in the same plane the cords for the lower sash are bent around the little direction sheaves 16, passing over the top of the guide ledges 18 on the lower sash and are accommodated in a groove in the sash behind these ledges 18.

The moment the latch 4 is released the tension of the cords around the direction sheaves 16 tends to throw the top of the lower window outward so as to stand in a plane parallel with the lower sash and forward of the parting strips 5, so that the lower sash may be raised into a plane parallel with the upper sash, or the supper sash pulled down. i

The suspension of the weights 13 by the pulleys 14 in the central looped portion of the window cords allows for perfect adjust- I a sash to be turned out of the window casing,

ment so that either window may be worked independently of the other and at the same time the windows will always be counterbalanced.

In case it is desired to clean or take out either of the windows, the window to be operated is lowered to the bottom of the casing and the hinged rails 8 turned on their hinges into the room so as to leave the sides of the casing below the top inside ledges 7 flush with the side edges of the sash; the sash adjacent to its lower rail has a plate 19 at each side which has a cam slot 20 open to the front so as to form a hook portion which is in line with projecting lugs or pins 21 on the window casing whenever the sash is at its lowest point.

If the side rails are opened as above described and the lowermost sash is then pulled outward, the cam slots 20 will receive the pins 21 as pivots; and these pivot pins prevent the lower end of the sash from flying upward under the tension of the counter weights. If it is desired to take out the sash the hinged rails 8 are opened as above described, and the sash to be removed is lifted so as to clear the pivot 21, whereupon the whole sash may be swung into the room.

lVhenever the hinged rails S are closed they are locked in place by suitable means, asthe small spring latches 22, and the pivot pins 21 are suitably accommodated as in the recesses 23 of the widened portion of the hinged rails 8.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. The combination in a window, of a win dow frame, sashes slidable therein, a parting strip and an inner guide rail between which the lower sash is slidable, an outer guide rail between which and said parting strip the upper sash is slidable, and hinged sections forming lower continuations of the inner guide rail and adapted to open to allow said hinged sections being substantially right-angular in cross-section and having front portions adapted to rest flat against the body of the window casing to form a waterproof joint.

2. The combination in a window, of a window frame, sashes slidable therein, an

outer guide rail on the casing along which the upper sash slides and against which the lower sash seats when the window is closed, a parting strip extending approximately half the length of the window casing with the lower end of said strip terminating above the top rail of the lower sash when the latter is closed, an inner guide rail between which and said parting strip the lower sash is slidable to pass the upper sash, hinged sections forming lower continuations of the inner guide rail and adapted to open to allow a sash to be turned out of the window casing, said hinged sections being sub stantially right-angular in cross-section and having front portions adapted to rest flat against the body of the window casing to form a weather-proof joint.

3. In a window construction of the character described, the combination of a win dow frame, the upper sash, the lower sash, means permitting the sashes to both slide and swing in the frame a plate fixed to the lower rail of the lower sash near each side, said plates having cam slots opening toward the front, and projecting pins on the window casing adapted to engage said slots when the sash is at its lowest point, said pins serving as pivots about which the sash may turn.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

GUSTAV HOEHNE.
